Abstract:
The Pure and EDTA Capped ZnO nanoparticles were synthesized via Wet-Chemical method. The surface morphology of the Pure and EDTA capped ZnO nanoparticles have been studied using FESEM. The structural morphology of the pure ZnO nanoparticles has obtained in non-uniform manner. When we added EDTA as capping agent the surface morphology of the radial hexagonal shapes of the particles are individually separated when compared to the pure ZnO. From the X-ray diffraction (XRD) study, it reveals that the synthesized ZnO product has the hexagonal phase structure. The average crystallite size of the Pure and EDTA capped ZnO nanoparticles are 16.17 nm and 9.22 nm respectively. The synthesized samples were examined through UV-Visible spectrometer; the UV absorption at around 373 nm with the estimated direct band gap energy is 3.32 eV for pure Zinc oxide and is 3.25 eV for EDTA Capped ZnO.


Keywords:FESEM, XRD, UV-Vis, ZnO nanoparticles, EDTA.
